Soakaway question

[DXP55]

At our old house we had soakaways which then meant we didn't have to pay 7 Trent for disposing of our waste surface water. (NOT WASTE SEWER WATER) Does that still apply - I have rang 7 Trent and the bloke kept jabbering on about highway water but unfortunately with my hearing aid's I couldn't decipher a word he said.
So does anyone here with soakaways pay for the disposal of it even though it just soaks away.

I am just waiting till holiday is over then ring the vunerable help line (80) -see if I can get some sense out of them - although they were spot on when I went to a water meter.
